Work-around to get USB-C headset to work for calls (in Android smartphones)?

It is an interesting, albeit frustrating, phenomenon of late that manufacturers of soft- and hardware these days (including Huawei, Samsung and apparently also Google) release new products which do not function as advertized:

I use my usb-c setup for mostly listening to hi-res music, it’s annoying when I get a phone call and I have to disconnect my USB-c headphones to answer the call. Seriously Samsung needs to get there head out of the ass and fix this problem. How can every other flagship phone handle this including the OnePlus 6.


bump. So I did some bumming around. I don’t think it’s the equalizer that’s the problem. I think the phone app is incapable of routing calls through USB-C.

It’s 2018 and USB Type-C is still a mess


How USB Type-C Has Failed Android Smartphone Users

Here’s what I’m confronted with: Huawei P10 with up-to-date software as of 3 Sep 2018, build nr. VTR-L09 and “Dialer” app/process (?) version nr. and Huawei Active Noise Cancel(l)ing Earphones 3 (cm-Q3) where sound works and calls through other apps like WhatsApp works but not through the standard telephone app. Any ideas on how to route standard phone calls through another (trustworthy…) app?

Other than finding a viable work-around all I can do is to hope that a fix will percolate through eventually through an update…

Please help to suggest workaround to prevent docker from this security issue while still not have update patch

According to this news from these URL.

As the System Administrator Roles. I update Security Patch for OS Ubuntu 18.04.2 and Check Network / Firewall already. Our Docker version is 18.09.06. However I would like to find the best way to prevent docker’s system from this security issue until Security Patch is release.

Thank you.

Whatsapp workaround?

What I have:
– I don’t want to install Whatsapp on my phone because I don’t want it to access my personal data.
– There’s an organisation that requires me to use Whatsapp to communicate with them.
– These two statements are mutually exclusive….

What I want:
– Is there any way for me to use Whatsapp without installing it on my phone? (I already have a Whatsapp user account.)
– Alternatively, is there a way to install and use Whatsapp without giving it access to all my data? (Contacts, calendar, camera, photos, etc etc.) I use Android 7.1.2 because there’s no newer ROM for my phone.

I realize this might be offensive to some users (“use it or don’t!”) but please look past that. I’m trying to satisfy competing demands here.

Uploading of backdoor results in the server removing file extensions. Any workaround?

I am totally new within the scene of information security, but find it extremely interesting and thus taking a course at my university, where we have to break into a website/webserver. The website is an image sharing website. The website is badly secured and I am looking for a way to upload my php backdoor created through weevely.

I can without problems upload a php file to the server. The problem is that the server automatically removes the file extensions, which makes it impossible for me to access through weevely (or so I think). Is there anyway to access a backdoor, when the file extensions are missing or is there a workaround?

Apologize for the rookie question!

Thanks How the upload folder looks like

Buffer overflow return address with null byte, workaround

Practising BO using Free Float FTP Server 1.0 on Windows 7 SP1, done simple jmp esp examples on Win XP where system DLL are without rebase or ASLR, trying to write one for Win7 where I haven’t got any system DLL with rebase or ASLR disabled, I can still exploit it but it won’t survive reboot, so I’m very much left with opcodes from the FTPServer.exe but the problem is that they all use a low stack addresses (0x0040xxxx) , so they all end with NULL byte (eg, \xce\x11\x40\x00 ) and hence terminate my exploit. My question is what are the options, if any to workaround the NULL byte in address I want to use, more specifically I want to know whenever there is an option to use NULL byte at the end of return address if it is listed as a bad character?

extfs_fsck crash on macos 10.14.4. Any workaround or fix?

I am trying to mount an external HD with extfs, but apparently the latest unmount was non-successful, and now the disk requires an automatic fsck. When macos tries to perform the fsck, this happens

It brings the whole system down with it. The mac reboots.

Is this a known issue? I could not find anything googling. Do you have a workaround for it?

Disable (or workaround) form rebuild with managed_file field

I’m using the Form API to create a custom form. It has a managed_file field and some other fields, some of which are required. If any of the required fields are not filled in, the file upload for the managed_file field doesn’t work, and produces an error informing the user to fill out the required field first before the image upload can process.

I’m assuming this is because the form is being rebuilt when the form uploads, but is there a way to stop it from checking for required fields? Surely there is a way, as node edit forms have this functionality working.

Here is my form code (simplified):

function create_event_form($  form, &$  form_state) {    $  form['event_image'] = array(     '#type' => 'managed_file',     '#upload_validators' => array(       'file_validate_extensions' => array('jpg jpeg gif png')     ),     '#upload_location' => 'public://event_images/',     '#required' => FALSE,   );    $  form['event_name'] = array(     '#type' => 'textfield',     '#title' => t('Event Name'),     '#required' => TRUE,   );    $  form['submit_button'] = array(     '#type' => 'submit',     '#value' => t('Create Event'),   );    return $  form; } 

If event_name field is empty when attempting to upload a file, the upload will not process.

api limit workaround

Are there any ways to avoid limitation for api calls (5/sec)?

I need the info about transactions and balance (of certain account), UTXOs and the ability to broadcast my transaction.

Currently I am using public blockchain explorers such as

However they have limits on their calls, which is unacceptable for cases if my service in use of at least 1000-2000 people.

I am begginer, so after some surfing I understood that the only way to tackle that issue is by saving the info in my own database or run my own full nodes (for each currency I have – eth/etc/bitcoin/btc/doge/dash.. etc) which might be pretty expensive and time-consuming.

Can you suggest any good solution?

Thank you!
